regex - How to use regular expressions to parse HTML in Java?

Please can someone tell me a simple way to find href and src tags in an html file using regular expressions in Java?
And then, how do I get the URL associated with the tag?

Thanks for any suggestion.

Using regular expressions to pull values from HTML is always a mistake. HTML syntax is a lot more complex that it may first appear and it's very easy for a page to catch out even a very complex regular expression.

Use an HTML Parser instead. See also What are the pros and cons of the leading Java HTML parsers?
